Important Safeguards
WARNING: Fire and shock hazard. nVent RAYCHEM
heating cables must be installed correctly to ensure
proper operation and to prevent electrical shock and
fire. Read these important warnings and carefully
follow all the installation instructions.
• To minimize the danger of fire from sustained
electrical arcing if the heating cable is damaged
or improperly installed, and to comply with the
requirements of nVent, agency certifications, and
national electrical codes, ground-fault equipment
protection must be used on each heating cable branch
circuit. Arcing may not be stopped by conventional
circuit protection.
• Damaged heating cable can cause electrical arcing or
fire. Repair or replace damaged heating cable or
terminations. Contact factory for assistance.
• To prevent shock or personal injury, discon-
nect all power before repairing or modifying the
heating cable.
• When drying out cable, care must be taken not to trap
moisture as this could cause the cable to burst, pos-
sibly causing injury.
